What owners reported
Source: NHTSA complaint databaseOwners of the 1 model year this bulletin names have filed 143 complaints with NHTSA since 2015. 51 of them name Electrical System, Power Train — the same broad component group this bulletin is filed under. NHTSA groups complaints coarsely, so that means the same area of the vehicle, not necessarily the same fault.
The start/stop warning light came on for the second time on my 2019 Durango. I had both batteries replaced the first time and now, at 18,500 miles it came on again even though I drive it daily on both highway and local roads. This time, the warning only came on once but the start/stop feature was affecting the performance of the truck.

The transmission sounds and feels like it is winding up and then shifts hard. This genrally happens right after I take off. It also sounds like it winds up at speed and then doesn't shift into overdrive, even thought it shows that it is is gear 8. This is not a one time occurrence, it happens everyday.

A complaint is one owner’s account, not a defect finding, and a bulletin is not a recall. Nothing here says this bulletin was issued because of these complaints, or that the repair it describes fixed them. Complaint files on this site begin in 2015.

Common questions
Source: NHTSA, 49 CFR 579.5Is Dodge 1810123 a recall?

Is the 1810123 repair free?
Not automatically. A service bulletin describes how to diagnose or repair a condition; who pays depends on the warranty in force, any extension, and the dealer. Quoting the number can save a diagnosis either way.
Which vehicles does 1810123 cover?
The manufacturer filed it against 1 model year: 2019 Dodge Durango. Whether one particular vehicle is affected is a matter of its VIN and its build, not its model year alone.
